As we don't need to duplicate 32/64-bit ISA defititions,
this series remove the duplicated 64-bit variants,
simplifying the overall.

Changes done automatically with my editor using "find
and replace".

While the 'ISA_MIPS_Rx' form is shorter than 'ISA_MIPS_RELx',
which one is the clearer?

Regards,

Phil.

Move CPU_MIPS5 after CPU_MIPS4 :)

MIPS 64-bit ISA is introduced with MIPS3.
No need for another bit/definition to check for 64-bit.

Simplify CPU_MIPS64 definition as CPU_MIPS5 contains
CPU_MIPS4 which contains CPU_MIPS3 which contains ISA_MIPS3.

Oops, I shall amend my reviewed by tag, just found a issue.

Use the single ISA_MIPS32R2 definition to check if the Release 2
ISA is supported, whether the CPU support 32/64-bit.

For now we keep '32' in the definition name, we will rename it
as ISA_MIPS_R2 in few commits.

After this change, 32-bit CPUs emulated with TARGET_MIPS64
and got CP0.Status.KX and CP0.Status.UX accidentally set won't
emit RI exception.

Probably we need to check ISA_MIPS64 when calculating
MIPS_HFLAG_64 and setting ksux in cpu_mips_store_status?

Thanks.

Sorry I respin v2 before noticing this reply.

32-bit CPUs shouldn't have MIPS_HFLAG_64 set, regardless
the build used. So check_mips_64() will emit it...

Anyhow, I'd rather remove 32-bit CPUs from 64-bit build unless
we are sure this works.

Use the single ISA_MIPS32R3 definition to check if the Release 3
ISA is supported, whether the CPU support 32/64-bit.

For now we keep '32' in the definition name, we will rename it
as ISA_MIPS_R3 in few commits.

To avoid holes in the insn_flags type, update the
definition with the next available bit.
